Enrique Hertzog assumed office as the 42nd president of Bolivia on 10 March 1947, and his term ended upon his resignation on 22 October 1949.

Nonetheless, Hertzog attempted to form a national unity cabinet and invited the PL to join in alliance with the new government, a fact which upset PURS leadership as well as Vice President Urriolagoitía.

[19] Guachalla was replaced as Foreign Minister by Tomás Manuel Elío who would serve his fifth and final nonconsecutive term.

Hertzog's fourth cabinet, formed on 1 March 1948, saw Adolfo Costa du Rels appointed Foreign Minister.

[21] At just two days from 9 to 11 August, the term of office of Julio Céspedes Añez as Minister of Work and Social Security is the second shortest term for any Bolivian government minister after Juan José Torres who served for just one day from 5 to 6 November 1964 during the government of René Barrientos.

Following subsequent election-related violence, PURS leadership lost confidence in Hertzog and forced him to hand power under the pretence of a nonexistent illness to Vice President Mamerto Urriolagoitía on 7 May.
